300. High or low ligation of the inferior mesenteric artery during curative surgery for rectal cancer

Abstract

Background: In rectal cancer surgery, the position of arterial ligation can affect genito-urinary function, bowel function, oncological outcomes, and the incidence of anastomotic leakage in low ligation preservation of the autonomic nerve, increased blood supply, decrease in anastomotic leakage. Oncological safety and tension-free anastomosis remain drawbacks. High ligation decrease perfusion and innervation of the proximal limb allows for enbloc dissection of the node metastases at and around the origin of the IMA. No conclusive evidence to improved survival.
